Form is a UI component used for the layout and alignment of form elements. Like the Flex Form Class, it contains multiple vertically positioned component items with label arrangement determined by width. Additionally, it supports data collection and validation implemented in a corresponding validation and data manager class.

Initializing a Form with ActionScript
To add a Form to your application with ActionScript, you must first include the Form component in your library. To do this, simply drag it from the Components panel directly to the library, or drag an instance to the stage and immediately delete it (the component will stay in your library). You must also import the following class in your class or frame script:
Form class generates the form and the
FormDataManager class collects data and validates it. There are several ways to create a form using the Form class. In this implementation, will create an array of
DisplayObjects to be used as elements in the form and set it as the
dataSource of the Form class instance.
Like any other Flash display object, you must add a Form to the display list by passing it to the
addChild method on the intended parent. The following example instantiates a Form, populates it with pre-initialized TextInput components and adds it to the display list of its parent.
